Took another crack at getting the map box to fit. It was clear that the length of the map box was conflicting with the avionics tray. So, I ended up cutting about 6" off of the box and reinstalling the back of the box. That did the trick as long as I dropped the trap door that the fuses and wiring are on. The door won't close because the wiring is in the way. So, I will have to reroute the wires again. On the pilot side of the top skin, I put the scat tube on the NACA vent and eyeball vent and then closed up the top skin. I riveted the top skin supports on both sides of the top skin.
